CentOS is one of the most preferred Linux-based server Operating Systems to choose from. It is employed by many website hosting service providers, since it is very stable, reliable and secure, not to mention that it is freely customizable, since it's an open-source Operating System. CentOS is used for production servers, as it is also very quick and takes minimal system resources. Furthermore, you'll be able to set up and run any web app, as long as it can run on a Linux machine. If you use a CentOS-powered server, you are able to update any part of your Operating System in accordance with your specifications. The fact that CentOS is absolutely free also means that you'll need to pay just for your server, but not for any sort of license fees, which will decrease your overall expenses. A huge group of developers and users is behind CentOS, so if you ever encounter any problems, or you're simply unsure how to perform a specific task, you'll be able to find a solution very quickly. An important advantage of the OS is also the fact that each version is officially supported and updated for at least ten years, so that you will always have a secure and dependable software environment.
